Application filed January 13, 1919.' 1Seria1 No. 270,833.

T 0 all whom it may concern:

Be it known that 1, CHARLES UnBnLMEssnR, a subject of the German Empire, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Variable Supports for Cuttin Tools, of which the following is a clear, full, and exact description.

My invention relates to an improvement in cutting tool supports such as described in my pending application filed November 7th 1918, Serial #261,581.

The object of my invention is to provide a movable cutting toolholder in a supporting structure, said supporting structure to contain a movable guide for the cutting toolholder, which guide is operated by head-on pressure against the work, or liead-on pressure against the guide itself.

Referring to the drawings,

Fig. 1 is a top view of a complete tool embodying the principle of head-on pressure against the work, the proper amount of transversal movement being compounded by leverage.

Fig. 2 is a side elevation, partly in cross section.

Fig. 3 is a front view.

Fig. l is a side elevation.

Fig. 5 is a modification and shows a top view of a complete tool embodying the principle of head-on pressure against the work, the proper amount of transversal movement being obtained. by means of a sliding guide.

Fig. 6 is a front view of Fig. 5, partly in section;

Fig. 7 is a right side view of Fig. 6, also partly in section.

Fig. 8 is a left side view.

As .shown in Fig. 1 the main support 1 carries a slidable tool support 2, being held in position by front plate 3. A. tool bit at is fastened in 2 by means of screw 5. The work stock bar 6 (see Fig. 1) passes through front plate 3, against the piston 7, said piston 7 slides in the main support 1, abutting against a lever 8 on the abutment portion 7. Lever 8 is pivoted on the main frame 1 on axis 9 and has another lever 10 abutting a screw point 11 against the 3rd lever 12. Said lever 12 is pivoted in the main support 1 at axis 13 from which point projects the 1th lever 14. Said lever 14: has a stud 15 which engages the groove 16' in the graduated screw knob 16, by which knob the position of the tool bit relative to the work can be adjusted to a minute fraction of an inch; the screw knob 16* is mounted upon the threaded stub 17 and is part of the slidable tool bit support 2. As the work bar pushes upon the piston a preproportioned amount of movement is imparted to the member 2 by means of the levers 8, 10, 12 and 1 1. Springs 18 and 19 are employed to bring the piston 7 back to its original position after the finished work has been withdrawn.

Referring to F 5, which is a mo diiica tion, 21 is the main support. The slidable tool. support 22 is being held in position by the frontplate 23, and tool 2 1 is fastened in 22 by means of screw 25 (see Fig. 6) the work stock bar (see Fig.8) passes through the front plate 23 against the piston 27, said piston 27 slides in the main support 21. Now this piston 27 carrieson the extension 28 a guide. 29 which, slides back and forth wit-h the movementof the piston 27.

30 is adjustably fastened to the slidable tool support 22. The slidable support 22 is held under pressure of spring 37 against the cruide 29, the piston is brought back to its first position after the finished work has been withdrawn by means of a lever 32, said lever having a slot 32 engaging a pin 33,

and said pin is part of the piston extension 28. The lever 32 is pivoted on axis 34 in the main support 21. The axis 3 1 has on. its lower extension a spiral spring which holds the lever 32 forward against the work. It is readily seen that the moving of the piston 27 moves the guide 29 which will impart to the tool-holder slide 22 whatever form the guide 29 has, and the roller 30 is adjustably mounted to the slidable support 22 by means of yoke 36, said yoke having a stud 36 extending through a knurled screw 37 which is mounted directly into the slidable tool support 22. It is readily understood that in this modification the amount of transverse movement to the slidable tool support is determined by the guide 29, but

said guide 29 is operated again'by head-on pressure against the work bar 26.

What I claim is:

1. The combination in a machine box tool, of a main support, a movable toolbit-holder, a work-holder, and a guidecarrying mem- Against this guide 29 lays a roller 30, which roller ber abutting the Work-bar in said holder, erning the toolbit-liolder by head-on pre said guide member imparting motion to the sure of the Work-bar.
